First, the price of plastic steel doors and windows
1. At present, the pricing of our plastic steel doors and windows is mainly based on the price per square meter: fixed fan area × fixed fan unit price+open fan unit price = total price of doors and windows.
2. The price per square meter of plastic steel doors and windows is mainly determined by the different types and sizes of materials. The price of plastic steel doors and windows ranges from 500- 1500 yuan per square meter, and the specific price needs to be determined according to different situations.
3. For different profiles, their prices are different. Usually, the price of a square meter of ordinary Ovi flat-open plastic steel window is around 600-700 yuan, and the price of flat-open door is around 500-600 yuan, and the push-pull type is cheaper. There are also some unknown brands of steel doors and windows, and the price of single-layer glass is generally around 150-200 yuan. Therefore, when we understand the price, we still need to be specific to a brand, so that we can accurately calculate it.
Second, only these steps are needed to buy doors and windows.
1, with or without steel lining
Real conch plastic steel door and window profiles have steel lining, while fake conch profiles have no steel lining. The presence or absence of steel lining is intuitive from the cross section, but not from the outside. But it can be distinguished in other ways. Take a magnet and suck it on the side to know if there is a steel lining. This method is especially suitable for identifying the true and false profiles according to the wall thickness of the profiles after the window is completed.
2. Protective film
The authenticity of conch plastic steel doors and windows can be identified from the protective film. The protective film of high-quality conch doors and windows is hot-pressed, and there are few small bubbles inside, while the inferior conch doors and windows are hand-pasted, so there are usually many small bubbles.
3. Profile color
The profile color of real conch plastic steel doors and windows is bluish white, while the profile color of fake conch is white and yellow, which is very different.
Therefore, the materials of our doors and windows are also varied. The same material has different manufacturing processes, different models and different prices, so you should judge and choose according to your actual situation when purchasing.
